Y GLOBE HOLDER nor.

1 Application filed December object to provide a globe. holding devicecapable of being clamped about or released from the neck of a globe, andwhich at the same time embodies the feature of simplicity as regards themanner. of effecting the clamping or releasing of the globe, and whicheliminates the necessity for clamping screws.

The holder embodying the resent inven tion is in the form of a split 7and adapted to encircle the neck of a globe, with provision for drawingthe ends together and for permitting the ends to spread apart to effectthe globe clamping and releasing respectively.

Further the invention resides in the means for drawing together orallowing the expansion of the ends of the band, this means beingpreferably embodied in one of the devices utilized to support the globeholder and globe.

Still further the invention resides in a globe holder having part or allthe characteristics above referred 'to, and addition.- ally shaped so asto afford a degree of adjustability to adapt the holder to globes whosenecks are of slightly varying diameters.

The inventionmay be further briefly sum marized as consisting in certainnoveldetails of construction, and combinations andarrangements of partswhich will be described in the specification and pointed out in theappended claims.

In the accompanying sheet of drawings, Fig. 1 is a side elevation of myimproved holder applied to, or in supporting relation to a globe;;Fig. 2is an enlarged plan view of the holder removed from the globe showingthe holder in full lines when it is contracted and its ends clamped aswhen the holder is supporting the globe, and showing by dotted lines theends released and the holder somewhat expanded to permitthe release orremoval of the globe; Fig. 3 is a fragmentary perspective view showinghow LIGHTING FIXTURES.

one of the holder supporting devices may be utilized to hold the ends ofthe band or holder in globe supporting position; Fig. a

is a similar View showing the ends released or spread; and Fig. 5 is aperspective view showinga lamp equipped with my invention. .7

In the accompanying sheet of drawings, 10 represents the globeof a. lampfixture,

which giobe may have any suitable design or shapeand is adaptedtoenvelop a lamp .inthe customary manner, this fixture being particularlya ceiling fixture wherein the lamp is supported from an upperwall or'ceiling somewhat in the manner illustrated in Fig. 5.] The globe hasthecustomary re-j duced neck portion'surmounted by a lip or flange,indicated at 10. The globe holder consists of a circular band 11 whichmay be formed of any suitable material, but pref erably from metalhaving. some degree of elasticity which will permit the contraction ofthe band to the position shown by full lines in, Fig. 2, and itsexpansion, as indi cated by dotted lines in, the same figure.

The band is. provided preferably at equallyspaced points with aplurality of loops 12 with circular outer portions and paral el innerportions,-as'shown in Fig. 2. The number ofthese loops may be varied andwill depend upon the number of points at which the holder and globe areto be supported, as by chains, or cords, or links.

In this instance the holder is to besupported at three points, andtherefore three such loops are provided. or devices are designed to beattached tothese loops, and as here shown they include endless straps orlinks 13 which form a permanent part of the holder andpass through Thesupporting means openings in the inner portions of'the loops P asclearly shown in the different figures, of the drawing. a Y

One of these'loops, designated 12* is split at a point indicated at 12,forming the two ends of the band which are adapted to be drawn togetherto contract the band and obviously due to the fact that the link isnarrow, the ends of the band at the loop 12 are held together or in theposition shown in Fig. 2, in which event the band is contracted or inconditionfor supporting the globe. On theother hand, when thelinkassociated with the split loop 12 is turned from vertical position tohorizontal position in'the manner indicated in Fig. 4, the ends of theband, or the parts of the split loop 12 can spring apart so as to allowthe band to expand. p

It will be seen therefore, that the locking otthe band in globesupporting position is brought about by one of the links or parts of theholder supporting means, and that when this link is in supportingposition it automatically retains or locks the band in its contractedposition. It will be seen also, that it is; only necessary to allow thelink 13 associated with the split loop 12 'to drop to horizontalposition as relieving this link 13 of the weight of the globe that theends of the holder are automaticallyflre leased-so that the holder canexpand.

Additionally another advantage follows from the use oi a holder in theform of a split band having the external loops lQand 12, and this liesin the tact that the loops provide a'certain amount of excess metal toenable the band to enlarge somewhat to permit it to'be used with a globesomewhat larger than the standard size normally intended to be used withthe holder, that is to say,should the external diameters of the.

necks oi the globes vary somewhat, or should the bands vary slightly insize, the lnwardly vxtendin )arallel sides of the loops 12 mav,

s l v expand so as to allow the holder to be clamped about a globe.having a relatively large size neck.

The holder and globe may be supported and connected to the lamp in anysuitable manner. For'example, in Fig. 5, the globe and globe holder forma part'otf a ceiling lamp designated asa whole by the referencecharacter 14. In this lamp there isa central fixture 15 which containsthe lamp proper, the top ofthis fixture being supported from above bysupporting members 16 and the links 13 or" the globe holderbeingconnected to the upper part ofthe fixture by supporting rods or links17.

It will be seen therefore, that I have provided globe holder which doesnot require holding screws, and whichat the same time embodies thefeatures of simplicity and utility to a high degree.

I do not desire to be confined'to the exact details shown, but aim in myclaims to cover all modifications which do not involve a de-, parturefrom the spirit and scope of my invention in its broadest aspects'Having described my invention, 1 claim:

Lit globe holder for a lamp, comprising a split band adapted to beextended about the neck of a globe, said band having portions adapted tobe drawn together or spread apart to permit the band to be contracted orexpandethand an elongated substantially flat endless link slidably and.rotatably engaging the endportionsot the band whereby when said link isin a positionin which it extends lengthwise alongside the band the band.is free to expand and when. said link is turned to a position at rightangles to the plane of the band said band' is contracted and held incontracted position. o

2. A globe holder comprising a split band adapted to encircle the neckoia globe, a plurality of holder suppoz-ftin'g links connected to saidband, and supporting members connected to said links, one said linksadjustably engaging the ends of the band adjacent the split and servingto hold said ends relatively close together or to permit them to spreadapart, depending upon the position that the llnk assumes with referenceto sald band.

3.1L globe holder for a lamp fixture comprising split band havingoutstanding ends at the point of the split, and a plurality of holdersupporting devices connected to the holder, one of said devices eugagingsaid ends of the band to hold the band contracted, said end engagingsupport 111,9; device belngmovable wlth respect to comprising a bandadapted to encircle the neck of a globe to be held, and provided with" aplurality of outwardly extending loops, one of the loops being dividedinto two parts forming a split band, and a plurality of holdersupporting. links extending through said loops, one of said linksserving to hold the two ends or portions of the split or divided looprelatively close together andto permit them to spread apart,

depending upon the position that said link assumes with reference tosaid loop.

In testimony whereof, I hereunto allix my WILFRID LUMLEY.
